The app works for a first-week beginner and for a music student preparing for exams. The exercises get harder only when you are ready for it.
Recognition, singing and dictation: intervals, chords, scales, cadences, progressions, solfege, melodic echo, vocal warmup and more.
The app tracks your accuracy on every interval, chord and scale, and adds new material only when the current one is solid.
Things you have learned come back for review just before you would forget them, so they stay learned.
Accuracy per interval, the pairs of sounds you mix up, per-skill scores and a practice calendar. You see exactly what to work on next.
37 achievements, XP levels and daily streaks. Not the reason to practice, but they help on the days you don't feel like it.
Sing intervals and melodies into the microphone. Live pitch detection shows whether you are on the note, sharp or flat.


You start by telling a major third from a perfect fourth, and you can end up transcribing melodies with rhythm. Each step on the way has its own exercise type.


ToneSeed records every answer. If you keep mixing up minor and major sixths, your next practice will have more of them, and less of what you already know.


Ear training works best in short, regular sessions, and coming back every day is the hardest part. Streaks, levels and achievements help with that, and the Learn tab explains the theory behind what you hear.
Learning your first intervals or working on harmonic dictation for an exam - there is an exercise for the level you are at, and one for the level after that.

Knowing why a progression sounds the way it does makes it easier to hear. The guides and tools in the app connect the theory to the sound, one interval or key at a time.
